Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0031] The main content of power supply reliability planning includes three aspects: evaluating the current situation, setting goals and planning the future. Its core lies in the reliability evaluation theory. By evaluating the current reliability level, reasonable development goals are formulated, and then feasible planning schemes are proposed according to the planning goals. This plan establishes a set of comprehensive index system of factors affecting power supply reliability. On the basis of proper classification, correct calculation and in-depth refinement of power outages, the system fully researches, summarizes and summarizes the factors affecting power supply reliability. , which provides an effective way and analysis method for reliability target formulation, evaluatio...

Abstract

The invention discloses a method for improving power supply reliability. The method comprises the steps of determining a system of power supply reliability influence factors; analyzing a reliability planning and improving measure; and determining a reliability planning scheme; wherein, the power supply reliability influence factors comprise a factor influencing the power failure times of various devices in different power failure types, a factor influencing the power failure duration of the various devices in different power failure types, and a factor influencing the power failure various devices in different power failure types. The method for improving power supply reliability analyzes relevance between a power supply reliability status index and each of the influence factors, and specifically an influence degree of each of the factors on the reliability index, constructs the complete and systematic system of the influence factors, and mines a weak link for the status reliability according to the system.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a method for improving power supply reliability. Background technique [0002] At present, in the power grid planning methods widely used in my country, the analysis of power supply reliability is usually based on accident prediction or quasi-quantitative analysis of the "N-1" criterion. This method is easy to operate and has strong practicability, but there is no clear goal in quantitatively improving the power supply reliability index, which is one of the reasons for the low average power supply reliability in my country. [0003] In recent years, the State Grid Corporation of China has studied reliability-based distribution network target grid planning under the large-scale planning system, and in this way strengthened the leading role of planning in construction. In some studies, in order to quantitatively analyze the reliability index in power grid planning, the reliability targe...
